Why would anyone leave a comment for an advertisement on IG?

Take for example this Landrover photo on IG:

https://www.instagram.com/p/BS5xqWvAj3c/?taken-by=landrover

What percentage of these comments do you think are real?

It's very easy to build a bot that leaves generic comments. This guy open sourced his code:

Maybe I'm missing something, but I can think of only handful of reasons to leave a comment for an ad like this.

  1. You are a bot.
  2. You are friends of the photographer.
  3. You are somehow associated with Landrover marketing.
  4. You really love Landrovers (???).
